Add a new person
Persons only get their own page in omdb if they have been mentioned as cast or crew member on at least one movie page. Creating new persons in omdb therefore always works via an omdb movie page where you create a link.
Basically: First check with a simple search (see: Search) that the person you want to create does not already exist in omdb. If you don’t find the desired entry, you can create a new one.
The procedure
Find a movie in which the person has acted (=actor) or otherwise participated in (=crew) or create such a movie (see: Create New Movie). Enter the person as actor or crew member by selecting the tab “Crew/Actors” from the table bar at the top of the page. Then click on the button “add actor” or “add person to crew” and follow the input dialog. The person will then be displayed as a cast or crew member. Clicking on the name will take you to the person’s page and you can edit it freely. You can also freely link to this page in articles.
